摘要: 植物激素是指在植物体内某些部位合成、可被运输到其他部位调控植物生长发育的微量有机物质,在植物生命活动中发挥重要作用。根系是作物吸收水分和养分的重要器官,其形态决定了作物获得养分和水分的能力。作物发达的根系与其抵抗干旱环境胁迫息息相关,而植物激素在作物根系发育中发挥关键作用,因此深入了解干旱胁迫下植物激素对作物根系发育的影响对农业的安全生产是至关重要的。本文就干旱胁迫下植物激素如何调控及不同激素协同调控作物根系生长发育的研究进行了概述,并讨论了激素在作物抗旱上应用的意义及将来可能开展的研究方向。

Abstract: Phytohormone is a kind of trace organic that are synthesized in parts of plants and can be transported to other functional parts of plants to regulate plant growth and development. As an important organ for crops to absorb water and nutrients, root system development determines the ability of crops to obtain nutrients and water. Recent studies indicate that the well-developed root system of crops is closely related to their resistance to drought stress and phytohormones play a key role in the root system development. Therefore, it is important to understand the effects of plant hormones on crop root development under drought stress. In this paper, we summarized recent evidences on the roles of phytohormones independently or synergistically affecting the crops root system development under drought condition, and discussed the significance of applying phytohormones in crop drought resistance research and the feasible research directions in future.
